Specifying the Default Attachment Content Format

Use the Internet Mail property page to specify whether outbound messages with attachments will be encoded using Multipurpose Internet Mail Extensions (MIME) or uuencode. This option can be specified by e-mail domain. These settings override the default format.

Settings configured in client applications can override the default setting and the settings specified by e-mail domain. If the client specifies no content format option and no match is found in the e-mail domain options, the default setting will be used.

Note Message content should be set for UUENCODE when transferring messages to Microsoft Mail 3.x with Microsoft Mail Gateway to SMTP.

Select the Internet Mail tab.
Under Attachments (Outbound), select MIME or UUENCODE.
Choosing MIME means that all attachments will be encoded using MIME, except when the client software overrides the option. If a MIME message is delivered to a non-MIME-aware client, the attachment may not be usable.

Option Description

Plain text A plain text MIME body part is generated for the message. If HTML is also selected, Microsoft Exchange Server provides both Hypertext Markup Language (HTML) and plain text in a MIME multipart/alternative message.

HTML A MIME body part in HTML is generated for the message. If Plain text is also selected, Microsoft Exchange Server provides both HTML and plain text in a MIME multipart/alternative message. HTML is an Internet standard that enables rich-text formatting such as bold, color, and italic to appear in messages.

Binhex Renders the message body as text with any attachments encoded by the BinHex method, which is commonly used in the Macintosh operating system to encode 8-bit data transmitted on the Internet.

Specifying the Default Character Sets

Use the Internet Mail property page to specify the default character set to be used when sending outbound and receiving inbound non-MIME messages. You can also specify the default character set for outbound MIME messages.

Note The Internet Mail Service should be configured to match remote SMTP hosts; otherwise, the characters that the recipient sees in the message may be misrepresented.

Select the Internet Mail tab.
In the Character Sets box, select the character set to be used with MIME and non-MIME messages.

Option Description

MIME For outbound messages, the setting is used only if the code page the message was composed in can map to more than one character set.

Non-MIME For outbound messages, the setting is always used.
For inbound messages, the setting is used no matter what the original character set was.

Option	Description
MIME	For outbound messages, the setting is used only if the code page the message was composed in can map to more than one character set.
Non-MIME	For outbound messages, the setting is always used. For inbound messages, the setting is used no matter what the original character set was.

Enabling Rich Text for Outbound Messages

Use the Internet Mail property page to configure the Internet Mail Service to send outbound messages using Microsoft Exchange rich text character formatting such as bold, color, and italic. This option also allows preservation of attachment position and the ability to include OLE objects as message attachments.

The attachment information in uuencode mode is included in a file called Winmail.dat. In MIME mode, this information is included in a body part tagged using the MIME content type of application/ms-tnef. If the recipient is not a Messaging Application Programming Interface (MAPI) client and rich text is enabled, the recipient may complain about receiving these attachments. To avoid this situation, use one of the following methods:

Disable rich text for the domain of non-MAPI recipients.
Disable rich text for each custom recipient.
Disable rich text in the sender's personal address book (PAB) entry for the recipient.
Disable rich text for the Internet Mail Service.

When the Internet Mail Service is used as a site connector, this option should be set to Always or User. Rich text should always be enabled when transferring messages to the Microsoft Mail Gateway to SMTP.

Note To set the Microsoft Exchange rich text for custom recipients, use the Advanced property page for custom recipients.

Select the Internet Mail tab.
Choose Advanced Options.
In the Send Microsoft Exchange rich text formatting box, select User, Always, or Never.

Option Description

Always Always send Microsoft Exchange rich text regardless of how the recipient is configured in the sender's PAB or how the recipient is defined as a custom recipient.

User Send Microsoft Exchange rich text only when enabled for the recipient. This is the default.

Never Never send Microsoft Exchange rich text regardless of how the recipient is configured in the sender's PAB or how the recipient is defined as a custom recipient.

Option	Description
Always	Always send Microsoft Exchange rich text regardless of how the recipient is configured in the sender's PAB or how the recipient is defined as a custom recipient.
User	Send Microsoft Exchange rich text only when enabled for the recipient. This is the default.
Never	Never send Microsoft Exchange rich text regardless of how the recipient is configured in the sender's PAB or how the recipient is defined as a custom recipient.

For information about setting these options by e-mail domain, see "Specifying Message Content by E-mail Domain" later in this chapter.

Disabling Out-Of-Office Responses

Some client applications can be configured to automatically generate replies to messages received while out of the office. You can stop out-of-office replies from being sent to the Internet.

Select the Internet Mail tab.
Choose Advanced Options.
Select or clear Disable Out of Office responses to the Internet. Select this to stop out-of-office responses to the Internet. This is the default. Clear to allow out-of-office responses to the Internet.

For information about setting these options by e-mail domain, see "Specifying Message Content by E-mail Domain" later in this chapter.

Disabling Automatic Replies to the Internet

Some client applications can be configured to automatically generate replies to messages. You can stop these messages from going to the Internet using the option in the Internet Mail property page.

Select the Internet Mail tab.
Choose Advanced Options.
Select or clear Disable Automatic Replies to the Internet. Select this to suppress automatic replies to messages received by the Internet Mail Service. This is the default. Clear to allow automatic replies returned to the Internet.

For information about setting these options by e-mail domain, see "Specifying Message Content by E-mail Domain" later in this chapter.

Disabling Display Names for Outbound Messages

The Internet Mail Service can be configured to send outbound messages with the sender's display name in addition to the sender's e-mail address. The display name is usually the full name of the sender. For example, Bill Lee's e-mail address might be billl@fab.com, and his display name Bill Lee.

Use the Internet Mail property page to enable or disable sending display names with outbound messages. To view the display name for a recipient, use the recipients container E-mail Addresses property page.

Select the Internet Mail tab.
Choose Advanced Options.
Select or clear Disable sending Display names to the Internet. Clear this to enable display names for messages sent through the Internet Mail Service. This is the default. Select to disable display names for messages sent through the Internet Mail Service.

For information about setting these options by e-mail domain, see "Specifying Message Content by E-mail Domain" later in this chapter.

Specifying Message Content by E-mail Domain

If you want to use different encoding methods, character sets, and message sizes for individual domains, use the E-Mail Domain option in the Internet Mail property page. These settings will override the default message content information and allow you to configure individual domains separately.

For example, you may want to use the MIME encoding method for the subdomain sales.fab.com and the uuencode encoding method for the domain fab.com. To do this, list the subdomain before the domain.

Note Uuencode and rich text should be specified when transferring messages to the Microsoft Mail Gateway to SMTP.

Select the Internet Mail tab.
Choose E-Mail Domain.
In the E-Mail Domain dialog box, choose Add.
Select the maximum message size, attachment encoding method, and character set options for this domain.

Option Description

E-Mail Domain Type the domain name. Subdomains and FQDNs are allowed. IP addresses and wildcard characters are not allowed. The Internet Mail Service will search the list starting at the top and will move down until a match is found. Therefore, subdomains should be listed before domains.

Maximum message size Specify the maximum number of kilobytes (KB) for outbound messages or select No limit.
The maximum message size specified in the General property page of the Internet Mail Service takes precedence if it is lower than this value.

Attachments (outbound) Select an encoding method for message attachments. Settings chosen in the client may override this option. If the client specifies none, and a domain match is not found, the Internet Mail Service default encoding method will be used.

Advanced Options Choose whether to specify options such as Microsoft Exchange rich text, word-wrap, and automatic replies.

Character Sets Select the character sets that will be used for content conversion.
